Bab el-Mandeb Strait: Why It Matters for Oil and Trade

Sometimes, it does not take a major war or the complete closure of trade routes to trigger a global crisis. Simply raising concerns about the security of a narrow waterway can affect financial markets, oil prices, shipping costs, and even the prices of the everyday goods we consume.

One of the most important of these waterways is the Bab el-Mandeb Strait—a strategic passage connecting the Red Sea to the Gulf of Aden and the Indian Ocean. Every day, millions of barrels of oil and enormous volumes of global trade pass through this route. As a result, any military tension or security threat in the area is not merely a regional issue; it has the potential to disrupt global supply chains and influence economies around the world.

In recent months, attacks on commercial vessels and rising regional tensions have once again pushed the Bab el-Mandeb Strait into the spotlight of global economic and geopolitical news. But why is this waterway so important? Could it actually be closed? And if that happened, what would be the consequences for oil markets, global trade, and consumers?

In this article, we answer these questions and explain how a relatively narrow maritime passage has become one of the world's most critical economic chokepoints.

Where Is the Bab el-Mandeb Strait, and Why Does It Matter?

The Bab el-Mandeb Strait is located at the southern entrance to the Red Sea, between Yemen on one side and Djibouti and Eritrea on the other. It connects the Red Sea to the Gulf of Aden and, ultimately, the Indian Ocean.

Ships traveling from Asia or energy-producing countries in the Middle East to Europe typically pass through the Bab el-Mandeb before entering the Mediterranean Sea via the Suez Canal. For this reason, the Bab el-Mandeb and the Suez Canal are often considered two interconnected sections of one of the world's most vital trade routes.

Interestingly, the name "Bab el-Mandeb" translates to "Gate of Tears" or "Gate of Grief," reflecting its historical significance.

At its narrowest point, the strait is only about 26 kilometers (16 miles) wide. The presence of Perim Island divides the passage into two navigation channels, creating a geographical bottleneck. This makes the route particularly vulnerable to security threats such as missile attacks, drone strikes, or naval mines.

Its true importance, however, becomes clear when considering the enormous volume of global trade that depends on this strategic passage.

Why Is the Bab el-Mandeb Strait One of the World's Most Important Trade Chokepoints?

The importance of the Bab el-Mandeb extends far beyond oil. It serves as one of the principal maritime corridors connecting Asia and Europe.

Estimates suggest that around 12% of global trade and nearly one-quarter of the world's container traffic passes through the Red Sea route.

In the first quarter of 2026, approximately 5.4 million barrels of crude oil and refined petroleum products moved through the Bab el-Mandeb every day.

However, energy is only part of the story. Millions of tons of goods also transit this route, including:

Mobile phones and electronic equipment

Clothing and textiles

Food products

Automotive parts

Industrial raw materials

For this reason, disruptions in the Bab el-Mandeb affect much more than oil prices. They can increase transportation costs, manufacturing expenses, and ultimately the prices consumers pay for everyday products.

Perhaps most importantly, the strait does not have to be completely closed to create economic disruption. Even the perception of rising security risks can alter the behavior of global shipping companies.

Does the Bab el-Mandeb Need to Be Completely Closed to Trigger a Crisis?

A common misconception is that only the complete closure of the Bab el-Mandeb Strait could disrupt the global economy. In reality, the situation is far more nuanced.

In global markets, the possibility of danger can be almost as influential as the danger itself. Even if ships remain physically able to transit the strait, the increased risk of missile attacks, drone strikes, or maritime assaults may be enough to make many shipping companies reconsider their routes.

Shipowners then face a difficult decision: Is it worth sending a vessel worth hundreds of millions of dollars, carrying valuable cargo, through a high-risk area? Or is it better to choose a much longer but safer alternative?

At the same time, marine insurers often raise war-risk insurance premiums and may restrict coverage for certain types of losses. These additional costs can make transiting the Bab el-Mandeb significantly less attractive from a commercial perspective—even if the strait remains technically open.

As a result, many shipping lines choose to bypass the Red Sea and the Suez Canal altogether, rerouting vessels around the Cape of Good Hope at the southern tip of Africa. While this route offers greater security, it also substantially increases both shipping time and transportation costs.

But what exactly are the consequences of this detour for global trade, and why are shipping companies willing to absorb such significant additional costs?

Why Do Ships Change Their Routes, and What Does That Cost?

Shipping companies typically decide to reroute vessels when the cost of risk outweighs the advantage of taking the shorter route.

A commercial cargo ship may be worth hundreds of millions of dollars, while its cargo can be critical to multiple businesses. As a result, sailing through an area where missile or drone attacks are possible represents a significant risk.

In such situations, many companies choose to divert their vessels around the Cape of Good Hope at the southern tip of Africa instead of passing through the Red Sea.

Although this alternative route is safer, it comes with substantial costs:

It adds approximately 10 to 14 days to the voyage.

Fuel consumption increases significantly.

Crews spend more time at sea.

The effective capacity of the global shipping fleet declines.

Freight rates become more expensive.

The World Bank has previously estimated that rerouting a single vessel around Africa can add around $1 million in extra fuel costs for a round trip.

A clear example occurred in 2024, when escalating attacks prompted many of the world's largest shipping companies to avoid the Red Sea, leading to higher global shipping costs.

But where did this crisis actually begin?

The Origins of the Bab el-Mandeb Crisis: The Houthis, the Yemen War, and Regional Tensions

To understand why the Bab el-Mandeb Strait has become one of the world's most volatile maritime chokepoints, it is necessary to look back several years at developments inside Yemen.

The Ansar Allah movement, better known as the Houthis, took control of Sana'a, Yemen's capital, along with large parts of northern and western Yemen in 2014. This marked the beginning of a conflict that later expanded when a Saudi-led coalition intervened in support of Yemen's internationally recognized government.

The war continued for years, causing not only extensive military destruction but also one of the world's worst humanitarian crises. Although a ceasefire in 2022 reduced the intensity of direct fighting, neither the conflict nor the underlying political, security, and economic disputes were fully resolved. As a result, Yemen remains one of the Middle East's most unstable countries.

How Did the Gaza War Bring the Bab el-Mandeb Back into the Global Spotlight?

Following the outbreak of the Gaza war in late 2023, the Houthis announced that they would target ships they claimed were linked to Israel. According to the group, these attacks were intended to pressure Israel and demonstrate support for the Palestinian people.

In practice, however, determining a vessel's actual affiliation is often far from straightforward. In the shipping industry, a vessel may be registered in one country, owned by a company in another, operated by a third, and carrying cargo belonging to multiple businesses from different nations.

This complexity created widespread concern among shipping companies, many of which feared they could become targets even without any direct connection to Israel. The resulting uncertainty significantly increased the perceived risk across the maritime industry, prompting numerous companies to reroute their vessels.

The Attacks That Reshaped Global Trade

Throughout 2024 and 2025, dozens of attacks on commercial ships were reported in the Red Sea and around the Bab el-Mandeb Strait. Some caused severe damage or even sank vessels, while others resulted in casualties among crew members.

These attacks involved a wide range of weapons and tactics, including:

Ballistic missiles

Anti-ship missiles

Suicide drones

Fast attack boats

Unmanned surface vessels

Potential naval mines

One striking feature of these attacks is their cost imbalance. Compared with the enormous value of commercial ships, many of the weapons used are relatively inexpensive. A single drone or unmanned boat can threaten a vessel and cargo worth hundreds of millions of dollars, while defending against such threats requires advanced naval forces, sophisticated radar systems, and highly expensive interceptor missiles.

As a result, even if most attacks are successfully intercepted, only a handful of successful strikes are enough to drive up insurance costs, increase shipping risks, and encourage companies to seek alternative routes.

However, this crisis extends far beyond Yemen and the Houthis. Behind these tensions lies a broader competition among regional and global powers, making the Bab el-Mandeb one of the world's most sensitive geopolitical flashpoints.

The Roles of Iran, the United States, and Europe in the Bab el-Mandeb Crisis: Can the Tensions Be Contained?

As attacks on commercial shipping intensified, the Bab el-Mandeb crisis evolved from a domestic Yemeni conflict into a major international security issue. Today, this strategic waterway sits at the intersection of regional and global interests, where political or military developments can quickly influence global trade and energy markets.

Iran's Role in the Bab el-Mandeb

Iran is widely regarded as the Houthis' closest regional supporter. Western governments and Saudi Arabia have repeatedly accused Tehran of providing the group with weapons, military training, and technology. Iran has denied these allegations, insisting that the Houthis act independently, although it acknowledges close political ties.

Because of this relationship, tensions involving Iran, the United States, or Israel often lead to renewed concerns about the security of the Bab el-Mandeb. Many analysts argue that the strait could become an indirect tool for exerting pressure on global trade and energy markets, even without direct Iranian military involvement.

The Response of the United States, the United Kingdom, and Europe

In response to attacks on commercial vessels, the United States, the United Kingdom, and several allied countries increased their naval presence in the Red Sea. At the same time, the European Union launched Operation Aspides, a defensive naval mission designed to protect commercial shipping. The mission has been extended until 28 February 2027.

Beyond escorting merchant vessels, the United States and the United Kingdom have conducted multiple airstrikes against Houthi positions in Yemen in an effort to reduce the group's missile and drone capabilities. However, many experts believe these operations alone cannot eliminate the threat entirely.

The reason is straightforward. After years of conflict, the Houthis have gained extensive operational experience and have dispersed much of their military infrastructure across mobile, concealed, and decentralized locations. Consequently, a limited number of airstrikes is unlikely to eliminate their capabilities completely.

Moreover, each new military operation carries the risk of escalating the conflict and drawing additional regional actors into the crisis—a development that could further threaten one of the world's most important maritime trade routes.

Recent Tensions in the Summer of 2026

In July 2026, tensions entered a new phase once again. The Houthis announced that they would impose what they described as a naval blockade on vessels linked to Saudi Arabia, saying the move was a response to pressure on areas under their control and the attack on Sana'a International Airport.

At the same time, reports emerged of attacks on Saudi oil tankers and certain energy facilities, raising fresh concerns about the security of shipping in the Red Sea.

Data from Kepler also showed that on July 26, 2026, only 11 cargo vessels transited the Bab el-Mandeb Strait—the lowest daily volume recorded in several months. During the same period, some oil tankers rerouted their voyages, others remained stationary while awaiting further instructions, and many chose the longer route around southern Africa.

These figures demonstrate that even without a complete closure of the Bab el-Mandeb Strait, the mere possibility of attacks can alter shipping companies' behavior and disrupt the flow of global trade.

The key question, however, is this: How do these security threats ultimately affect oil prices, transportation costs, inflation, and the global economy?

How Does the Bab el-Mandeb Crisis Affect Oil Prices and the Global Economy?

One of the most significant consequences of insecurity in the Bab el-Mandeb Strait is its impact on the energy market.

In the oil market, prices are influenced not only by actual supply but also by expectations about future events. As a result, even if oil exports have not yet been disrupted, a higher perceived risk of disruption encourages traders to add a geopolitical risk premium to oil prices.

If oil producers and shipping companies are forced to take longer routes, the transportation cost per barrel of oil rises accordingly. Those higher costs can eventually spread across the broader economy, affecting airlines, manufacturers, logistics providers, and many other industries.

The consequences are not limited to oil.

If shipping containers arrive weeks behind schedule, manufacturers operating with limited inventories may face shortages of components or raw materials. In today's interconnected economy, the delayed arrival of even a single critical component can halt the production of complex products such as automobiles or industrial equipment.

Egypt: One of the Biggest Losers in the Bab el-Mandeb Crisis

Egypt is among the countries most directly affected by this crisis.

A significant portion of Egypt's foreign currency revenue comes from vessels transiting the Suez Canal. When shipping companies choose to bypass the Bab el-Mandeb Strait and the Suez Canal in favor of the route around southern Africa, Suez Canal revenues inevitably decline.

For an economy already struggling with inflation, external debt, and foreign currency shortages, this creates additional financial pressure. Beyond Egypt, ports and maritime service providers across the Red Sea region also suffer declining revenues.

Could This Crisis Fuel Global Inflation Again?

Higher shipping costs, rising energy prices, and more expensive imports can ultimately reinforce global inflationary pressures.

If these trends continue, central banks around the world may postpone planned interest rate cuts, as lowering rates while inflation is accelerating again could make price stability even more difficult to achieve.

For this reason, investors monitor far more than just reports of attacks in the Bab el-Mandeb Strait. They also closely watch oil market reactions, global shipping costs, inflation data, and central bank policy decisions. Together, these developments illustrate how a relatively narrow waterway in the southern Red Sea can influence economic decisions across the globe.

This leads to one final and fundamental question: Could the Bab el-Mandeb Strait actually be closed, or is that scenario primarily a psychological risk reflected in market sentiment?

Could the Bab el-Mandeb Strait Be Completely Closed? What Lies Ahead for This Crisis?

One of the most important questions surrounding the Bab el-Mandeb crisis is whether the strait could be completely closed.

From a military perspective, disrupting traffic through the strait is certainly possible. However, keeping the Bab el-Mandeb Strait fully closed for an extended period would be extremely difficult. The primary reason is its critical importance to the global economy, prompting major naval powers to work to preserve freedom of navigation in the area.

That said, an important point remains: a full closure is not necessary to trigger a global economic crisis. Even a significant reduction in vessel traffic can have major consequences.

In reality, financial markets often react more to risk and uncertainty than to the physical closure of a shipping route. If shipping companies perceive a region as too dangerous, they may voluntarily reroute their vessels—as has happened repeatedly in the Red Sea over recent years.

In such a scenario, the Bab el-Mandeb Strait remains physically open but loses part of its economic function because fewer ships are willing to transit through it.

What Will Determine the Future of the Bab el-Mandeb Crisis?

The future of this crisis depends on several political and security-related factors, including:

- The course of the war and political developments in Yemen

- The situation surrounding the Gaza conflict and broader regional developments

- Relations between Iran, the United States, Israel, and Arab countries

- The effectiveness of international maritime security operations

- Potential negotiations and diplomatic agreements among regional stakeholders

If regional tensions ease, shipping companies are expected to gradually return to the Red Sea and Suez Canal route, as it remains the shortest and most cost-effective maritime corridor connecting Asia and Europe.

However, rebuilding confidence will take time. Shipping companies are unlikely to resume normal operations until they are convinced that security has been restored on a long-term basis, rather than viewing the reduction in hostilities as merely temporary.

Conclusion

On a map, the Bab el-Mandeb Strait may appear to be nothing more than a narrow waterway separating Yemen from Djibouti and Eritrea. In reality, however, it is one of the world's most critical maritime chokepoints.

The strait serves as the vital link between the Indian Ocean, the Red Sea, and the Suez Canal, carrying millions of barrels of oil and enormous volumes of global trade every day.

Recent events have demonstrated that even without a complete closure, insecurity in this waterway can disrupt global supply chains, increase shipping and insurance costs, place upward pressure on oil prices, and ultimately affect inflation and economic growth across many countries.

For this reason, the Bab el-Mandeb Strait is far more than a geographical or military issue. It is a strategic intersection where politics, security, energy, and the global economy converge. A single shipping company's decision to reroute its vessels may appear to cause only a few days' delay, but on a global scale it can increase production costs, drive up consumer prices, and place additional pressure on households and businesses alike.

Ultimately, the future of this vital waterway depends primarily on reduced regional tensions and the restoration of lasting political stability. Until that uncertainty is resolved, the Bab el-Mandeb Strait will remain one of the world's most closely watched strategic locations for investors, energy market participants, and the global shipping industry.
